Abstract
Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images and a brightness setting of a light source which is configured to illuminate a display that is configured to display the video images, where the sequence of video images includes video signals. Then, the system determines an intensity setting of the light source on an image-by-image basis for the sequence of video images, where the intensity of a given video image is based on the brightness setting and brightness information contained in the video signals associated with the given video image. Next, the system synchronizes the intensity setting of the light source with a current video image to be displayed.
